TBH, it has always been surprising to me that this wasn't a default feature in Android. It couldn't be that difficult to add.

Then again, they want to support small storage sizes, so maybe discouraging the OS from growing too much with redundant 32 and 64 bit versions of base libraries is the real reason?

I don't think Android has a big priority on storage size, every APK bundles all of its dependencies (except for ART), so if multiple apps use the same exact library and version, that library's code will not be shared among them
